To all whom it may concern.-

Be it known that I, JOHN E. POTTER, a

citizen of the United States, residing at Sapulpa, in the county ofGreek and State of Oklahoma, have invented a new and useful Improvementin Means for Severing and Distributing Molten Material, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification, inwhich- Figure 1 is a plan view of certain portions of a glass workingmachine embodying my invention.

Fig. 2 is a section on the line IIII of Fig. 1. v

Fig. 3 is a top plan view of the carrier for the guiding anddistributing members, and Figs. 4:, 5, 6 and 7 are diagrammatic viewsillustrating the operation in diflerent stages.

My invention is designed to provide simple and effective means forsevering or separating a continuously flowing stream of molten material,such as glass, and distrib uting the severed portions successively intoa series of receptacles, such as molds. A further, and more specificobject is to accomplish this result without the necessity for at anytime supporting the flowing stream above the point of separation orseverance. A'still further object is to enable the severing to be donewhile the machine is in motion. My invention also provides means foraccomplishing the above stated objects which, when applied -to a glassforming machine, will be out of the way of the operations performed uponthe glass after it enters the forming receptacles or molds.

The nature of my invention will be best understood by reference to theaccompanying drawings in which I have shown a preferred embodimentthereof, and which will now be described, it being premised, how ever,that various changes can be made in the details of construction,arrangement and combinationof the parts, without depart ing from thespirit and scope of the invention as defined in the appended claims.Also that the invention is capable of application to various other formsof glass working machines. i

In these drawings the numeral 2 designates a vertical post or columnupon which is mounted a rotating table 3 of a glass working machine, thetable being rotated by any suitable gearing, suchi fas indicated at 4.Supported upon the tableld are a plurality of mold vessels. Inthexf'drawing I have shown the table as having'ten of these vesselswhich I have designated, respectively as A, B, G, D, E, F, G, H, I, andJ. 5 designates a sleeve member which is secured to the table 3 torotate therewith and which, at its upper portion, is provided with ahorizontal extension 6'. Formed in the upper surface of this extension 6is a plurality of radial grooves 7. In each of these grooves is aslidably mounted bar 8 which, at its outer end, carries a glass guidingand distributing member. These members also act as cutting or shearelements. Each of these members consists of a short upper horizontalheel portion 9 and a downwardly and laterally directed guiding anddistributing portion 9, which is formed with a gutter or trough 9". Theedge 9 formed at the junction of the outer surface of the portion 9 withthe upper surface of the portion 9, constitutes a shearing or cuttingedge, which is designed to cooperate with the cutting edge of a singleof the guiding and distributing members is provided for each moldvessel; and each of these members is curved so that when in operativeposition its center line will be directly over the center line of rotarymovement in the mold vessels. As these members rotate with the table infixed relation to the molds, so far as rotary movement is concerned,they are moved radially into and out of operative position by suitablemeans. In the arrangement shown, such means consists of a cam groove 12formed in the under side of the frame member 11 and engaged by ananti-friction roller 13 on each of the bars 8. The form of this camgroove is best shown in Fig. 1 and this figure, also clearly illustratesthe movement of the said may continuously flow such as a melting,

to prevent sticking of the glass thereto.

The operation is clearly shown in the dia- Iteferring first to Fig. 4,the mold A has been filled; and the mold B is directly underneath thecharging source and is directly receiving therein the flowing stream ofglass, the table 3 moving either continuously or intermittently in thedirection indicated by the arrows.

In Fig. 5 the continued movement of the table has brought one of theguiding and distributing members below the flowing stream of glass, andits gutter portion 9 is directing this flowing stream laterally into themold B. In Fig. 6 the said guiding and distributing member has beenbrought into shearing relation to the fixed shear element 10 and theflowing stream has been sheared, the portion of the glass below thepoint of separation continuing to flow into the mold B. When the partsreach the position shown in Fig. 7, substantially all the glass hasflowed into the mold B, and the. next succeeding mold C is broughtdirectly underneath the flowing stream.

It will be understood that the molds are successively filled in thismanner. The lateral extension of each of the guiding and members issuflicient to direct the glass mto its corresponding moving mold untilsuch time as the next filling mold has been brought into position toreceive the stream. In this manner there is practically no interruptionof the flowing stream,

and it is unnecessary toprovide any support to that portion of thestream above the point of severance. The severing is effected while themachine is in operation. With a uniform streamof molten material and auniform movement of the table, the molds will, therefore, receivemeasured charges substantially uniform in volume. The vertical grooves 9in the heel portions 9, provide for the continued flow of the glassafter its each severing operation, and prevent temporary support of theflowing stream on such heel portions.

It will be further notedfrom Fig. 1 that the cam groove12 does not actto advance a the guldi'ng and distributing members untiltheyrespectively approach thecharging st a tion'; and that said members arereuse" shortly after passing such station. In their retracted positionsthey are entirely out of the way of theperformance of subsequentoperations upon the glass in the molds.

My invention is capable of being apphed to various kinds of glassforming machines, is simple in its construction and posithe combinationwith a receptacle, and

means for movin the same below a source of molten material, of a guidingand distributing member rotatable with said receptacle and arranged toreceive and direct the glass laterally from the source into thereceptacle together with means for severing the flowing stream, theparts being so arranged that the front end of the severed stream isunsupported by the guide while the tail end of the severed stream isdirected into the receptacle by the guide; substantially as described.

2. In apparatus of the character described, the combination with areceptacle, and means for moving the same below a flowing stream ofmolten material, of a guiding and distributing member rotatable with themold, said member having a laterally and downwardly inclined flowchannel together with means for severing the flowing stream, the partsbeing so arranged that the front end of the severed stream isunsupported by the guide and distributing member while the tail end ofthe severed stream isdirected into the receptacle by the inclined flowchannel; substantially as described.

3. In a paratus of the character described, the com ination with areceptacle, and means for moving the same below a flowing stream ofmolten material, of a guiding and distributing member rotatable with themold, said member having a laterally and downwardly inclined flowchannel, and also acting as a cutting element, the partsbeing soarranged that the front end of the severed stream is unsuplportedby theguide while the tail end of t e severed stream is directed into thereceptacle by the inclined flow chan nel; substantially as described.
